In another variation, an inflatable tube 107 may beincorporated into the cushion assembly 55 which may attach to thevehicle body 13 either directly or via an intermediate piece, avariation of which is illustrated in FIG. 22. When inflated, the “I”shaped cushion assembly 91, 93, 95 may extend across the A-pillar 7, avariation of which is illustrated in FIGS. 19-20, may extend across thelower windshield 5 and hood 3, a variation of which is illustrated inFIG. 21, or may extend down the side of the fender and hood 3 avariation of which is illustrated with lobe 25 in FIG. 3. Any variety ofcushion configurations, such as an “L-shaped” cushion assembly and/or a“T-shaped” cushion assembly may also use similar approaches forachieving a local attachment.

Referring to FIGS. 23-25, in a number of variations, a pedestrianprotection airbag 81 may include an “L” shaped cushion assemblycross-section 111, 113, 115. At least one internal tether 117 may beincorporated into the cushion assembly 55 to maintain the cushion shape.In one variation, an internal cross-tether element 117 may beincorporated on tan L-shaped cushion assembly 111 at the location of thebend 112 and sewn to the internal walls of the cushion assembly 111, avariation of which is illustrated in FIG. 23. In another variation, aninternal cross-tether 119 element may be incorporated into the cushionassembly 113 at the location of the bend and sewn into a joint betweencushion pieces, a variation of which is illustrated in FIG. 24. Inanother variation, cross-tethers 121 may be incorporated into a onepiece woven cushion assembly having an “L” shape 115, a variation ofwhich is illustrated in FIG. 25. The cross tethers 121 may includestitching that may extend back and forth from loops or fixed attachmentsformed in a first side and a second side of the “L” shaped cushionassembly 115. The “L” shaped cushion assembly cross-sections 111, 113,115 may then be configured to glove or nest against the A-pillar 7 orsome other exterior surface of the vehicle such as the fender (notillustrated). It may also be configured to nest against the rearwardedge of a deployed hood, as illustrated in FIG. 48. Finally, the “L”shaped cushion assembly cross-sections 111, 113, 114 may also beconfigured to rest against a generally flat surface profile to raise thebent portion of the cushion away from the generally flat surface toprovide additional space for energy absorption during pedestrian loadingin a pedestrian impact.

A pedestrian protection airbag module 81 may include an inflator 129which may be used to inflate the cushion assembly 55 during deployment.The inflator 129 may be attached to the cushion assembly 55 in any of anumber of variations including, but not limited to, at least one clamp323 that attaches to the cushion's neck 48, a variation of which isillustrated in FIGS. 26 and 27.

In a number of variations, a pedestrian protection airbag module 81 maybe attached to the fender region 1 of a vehicle 13 and when deployed,the pedestrian protection airbag module 81 may push the hood 3 upward.In one variation, a portion of the cushion assembly 55 may deployunderneath the hood 3 and a portion of the cushion assembly 55 maydeploy above and beside the raised hood 3. In another variation, thecushion assembly 55 may completely deploy above and beside the raisedhood.

Referring to FIGS. 26-28, in a number of variations, an inflatorassembly 233 129 may be located in the pedestrian protection airbagmodule 81 partially underneath the fender 9 and partially underneath thehood 3 of a vehicle 13. The inflator assembly 233 may include aninflator 129 and at least one clamping feature including, but notlimited to, a clamp 142 which may surround a portion of the inflator 129and may hold the inflator 129 in place.

In a number of variations, when the pedestrian protection airbag module81 deploys, the inflator 129 may deploy in a way which may raise thehood 3. The clamps 142 that surround the inflator 129 may each include astud 162 which may interface with a hole in the module housing 143and/or a mounting bracket 460. The inflator 129 may route through theclamps 142 and may be temporarily attached in its undeployed positionvia clamp load, a frangible feature (not illustrated), or an element ofthe design that may prevent the inflator 129 from moving downward withrespect to the clamps 142, such as a ridge around the inflator body 130just above a clamp (not illustrated). The inflator 129 may be slideablewith respect to the clamps 142 with the forces generated by deploymentwhen deployment occurs. Upon deployment, gas may be dispelled from thebottom 141 of the inflator 129 causing the inflator 129 to push at leastpartially up past the pedestrian protection airbag module housing 143 sothat it may make contact with the hood 3.

In one variation, the cushion assembly 55 may be compressed/sandwichedbetween the inflator 129 and the hood assembly 3 when the hood 3 islifted (not illustrated). In another variation, the cushion 55 may notbe compressed between the inflator 129 and the hood assembly 3 when thehood 3 is lifted, a variation of which is illustrated in FIGS. 26-27. Inthis variation, a plug 140 may be broken out of the airbag modulehousing 143. As the inflator 129 pushes against the hood 3, a temporaryhood attachment 125 may be broken 127 allowing the hood 3 to lift up.Simultaneously with the inflator 129 movement, the cushion 55 may alsofill and deploy. As the cushion assembly 55 fills, it may push out oneor more flaps 131 of module housing material that may act as a cushionprotector from objects such as the hood 3. The cushion assembly 55 mayalso push the fender 9 or deployment door 19 out of the way and maycontinue to fill until it achieves its final position, a variation ofwhich is illustrated in FIGS. 2-4, 19-21, 47, 60 and 62.

An airbag module 81 with a moveable inflator 129 may be mounted outboardof a hood hinge mechanism 169, as part of one or more pedestrianprotection airbag modules 81 located in the fender regions 1 of avehicle 13. The airbag module 81 with the slideable inflator 129 mayalternatively be mounted inboard of the hood hinge mechanism 169 and maypush up on the hood 3 at a location between a left and right hood hingemechanism 169. In yet another alternative, the moving inflator 129 mayalso simultaneously push up on a portion of the fender 9, a portion ofthe A-pillar 7, and/or a portion of an adjacent trim piece that maycover a gap between adjacent components in the region of the inflator129 (none of these illustrated).

In any of a number of variations, the hood hinge 259 may be configuredto enable an upward force to detach, or partially detach, a hood 3 forwhich an inflator power source concept applies without limitation.During deployment, the inflator 129 may raise and may cause the inflator129 to reach a travel stop which may limit the inflator's 129 upwardmotion. In one variation, a lower clamp 142 may be contacted by a ridge144 around the inflator 129. The interference may be configured so thatthe parts 142, 144 may optionally wedge together so that the inflator129 may remain affixed in a raised position and may be prevented fromreverse travel if loaded from the top by a pedestrian impact event.Additional forms of mechanical travel stops and anti-reverse travelfeatures may be incorporated. A coupler 153 may be attached to the top137 of the inflator 129 which may contact and abut against the hood 3,fender 9, A-Pillar 7 or deployment door 19 when the inflator 129 deploysand lifts, a variation of which is illustrated in FIG. 28. The coupler153 may provide better geometric alignment and may lift an adjacentcomponent to the hood 3 along with the hood 3.

Referring to FIGS. 29-35, in a number of variations, an inflator 129 maybe located in the pedestrian protection airbag module 81 under a fender9 and beside the hood 3 of a vehicle 13. When the inflator 129 deploys,the inflator 129 may dispel gas from the bottom 141 of the inflator 129causing the inflator 129 to push upwards which may cause the inflator129 to contact a hood hinge mechanism 169 which may partially or fullydetach, deform, or otherwise allow the hood 3 to lift upwards, avariation of which is illustrated in FIG. 33. In one variation, theinflator 129 may be attached to two studs 162 that may be eitherintegral to the inflator body 130 or may be mounted on one or moreclamps 142 that in turn may be rigidly affixed to the inflator body 130,for example with one or more crimps. In a number of variations, theinflator 129 may be attached/mounted to a mounting bracket 460. In onevariation, the studs 162 on the inflator 129 and/or on the one or moreclamps 142 may extend through one or more slots 162 on the mountingbracket 460 and/or the module housing 143, an illustrative variation ofwhich is illustrated in FIGS. 32 and 33. The studs 162 may be slideablymounted in the one or more slots 163 in the module bracket 460 and/orthe module housing 143. The mounting bracket 460 may then attach theairbag module 81 to the vehicle 13. While the mounting bracket 460 andthe module housing 143 are typically separate parts, it may be possiblewith some designs to combine these parts. Gravity, clamp load, thebottom of the slot, and potentially a frangible feature (notillustrated) may hold the inflator 129 in the undeployed position priorto deployment. Upon deployment the inflator gases may propel theinflator 129 upward as the studs 162 slide upward in one or more slots163. The inflator 129 may then contact the hood hinge mechanism 169 tocause its detachment. When this occurs, an adjacent trim piece 170 maydeform and move out of the way if contacted by the hood hinge mechanism169 which may allow a portion of the hood hinge mechanism 169 and thehood 3 to lift.

In another alternative, the moving inflator 129 may also simultaneouslypush up on a portion of the fender 9, a portion of the A-pillar 7, or aportion of an adjacent trim piece that may cover a gap between adjacentcomponents in the region of the inflator 129 (none of theseillustrated). As the inflator 129 strokes upward, a plug 140 may bebroken out of the module housing 143 and may rise with the inflator 129.A triangular point 149 may be incorporated into the module housing 143which may act as a wedge against the upper inflator stud 162 which mayact as a travel stop and may prevent the inflator 129 from projecting alength out of the module 81 further than desired. The triangular point149 may also act as a wedge to lock the inflator stud 162 to it and thusmay function as an anti-reverse travel feature.

In a number of variations, the cushion 133 may fill with gas and inflatesimultaneously with the inflator 129 movement. The cushion assembly 55may push a fender 9, a fender 9 along with a separate deployment door,or a deployment door 19 out of its path and may continue to fill untilit achieves its final position, a variation of which is illustrated inFIGS. 2-4, 19-21, 47, 60, and 62. The module housing 143 may include aprotective flap attachment 151 which may prevent or lessen contactbetween the inflating cushion assembly 55 and the hood hinge mechanism169, a variation of which is illustrated in FIG. 33 and/or potentiallythe hood 3 or other adjacent components (not illustrated). The hoodhinge mechanism 169 may contain an open slot 165 in the lower portion173 of the hood hinge mechanism 169 which may allow the upper portion171 of the hood hinge mechanism 169 to raise upwards as the inflator 129deploys and pushes upward. The upper portion 171 of the hood mechanism169 may have a U-shape which may stabilize the lateral bolt 155 or otherprotruding structure. In another variation, a hood hinge mechanism 169may also include a link arm (not illustrated) in its configuration thatmay bend or move to enable the hood raising. In a number of variations,other portions of the hood mechanism may be extended to be under theairbag module where they may be contacted and moved during deploymentand other means of releasing the hood may be possible.

The inflator 129 may also be directly attached or abut to a portion thehood hinge mechanism 169 via a coupler 153, a variation of which isillustrated in FIG. 34. The coupler 153 may also directly attach or abutagainst separately or in addition to one of the following to help liftit during deployment: on a portion of the fender 9, a portion of theA-pillar 7, or a portion of an adjacent trim piece that may cover a gapbetween adjacent components in the region of the inflator (none of theseillustrated). The module housing 143 may be attached to the vehicle body13 using at least one fore-aft attachment 157, a variation of which isillustrated in FIG. 30, or at least one lateral attachment 159, avariation of which is illustrated in FIG. 31. The fore-aft attachment157 or the lateral attachment 159 may be attached to the vehicle body 13in any of a number of variations including, but not limited to, a bolt,a clip, and/or a bent tab going through a receiving hole. An airbagmodule 81 having a slideable inflator 129 may also be mounted at alocation inboard of the hood hinge mechanism 169 and may push up on thehood 3 at a location between the left and right hood hinge mechanisms169.

Referring to FIG. 89, in a number of variations, a module housing 143may contain a slot 170 that may surround a wedge housing 172 that inturn surrounds an upper inflator stud 162. The wedge housing 172 maycontain a wedge dowel 174 which may interact and wedge against both theangled wedge wall 178 of the wedge housing 172 and the module housing143 once the inflator has reached full stroke. This configuration mayact as an anti-reverse travel feature. The slot 170 may also beconfigured to include a weakened wall that may contain a deformableenergy absorbing surface 176. In this variation, if the hood 3 is loadedfrom the top, the inflator 129 and hood 3 may stroke downward in acontrolled manner as the deformable energy absorbing surface 176deforms. Other forms of wedging devices, such as other configurationsused in seatbelt pretensioners may be applied to this concept.

Referring to FIG. 90, in another variation, the module housing 143 maycontain a slot 180 that may surround an upper inflator stud 162. Theslot 180 may include a second slot 182 which may be constructed andarranged to accommodate a flexible element 184. The second slot 182 maybe placed at an angle. The flexible element 184 may comprise any of avariety of materials including, but not limited to, spring steel. As theupper inflator stud 162 moves upward, the flexible element 184 may flexwhich may allow the inflator stud 162 to pass by. If the hood 3 ispushed down and the inflator stud 162 attempts to reverse travel, theflexible element 184 may engage the inflator stud 162 and may act as ananti-reverse travel feature. The flexible element 186 may include ageometry with curved features 188 that may compress and may interactwith the sides of the slot 190, a variation of which is illustrated inFIG. 91, which may allow the flexible element 186 to deform in the slot190 and absorb energy once the inflator stud 162 has passed by, attemptsto reverse travel, and/or engages the top of the flexible element 186.

In another variation, a device may be configured which extrudes a metalstrip between ridged members or pulls a bent metal strip through rigidmembers to accomplish this energy absorption feature (not illustrated).Finally, it is possible for these anti-reverse travel and energyabsorption features to be directly integrated into the hood hingeassembly in any of a variety of ways including, but not limited to,placing it in one of the slots a variation of which is illustrated inFIGS. 36-41.

Referring to FIGS. 36-41, in a number of variations, a hood hingemechanism 181, 193, 207 may be configured so that a) without deploymentthe hood 3 may rotate about single pivot points on the left and rightsides of the hood 3 when it is being opened or closed and b) afterdeployment of the pedestrian protection airbag 81, the hood 3 may beretained to the vehicle body 13 when in a raised state.

In one variation, the hood 3 may be rotated about the lower end of aslot 187 when the hood 3 is opened or closed in normal usage and theupper portion 189 of a hood hinge mechanism 181 may be pushed upwardsduring deployment of the pedestrian protection airbag module 81. Theupper portion 189 of the hood hinge mechanism 181 and the lower portion191 of the hood hinge mechanism 181 may be connected by a bolt 185 whichmay be seated in a generally vertical slot 187 and may form the pivotfor the hood 3 when it may be opened and closed during normal operation,a variation of which is illustrated in FIG. 36. As the pedestrianprotection airbag module 81 deploys, the upper portion 189 of the hoodhinge mechanism 181 may be pushed upwards along the slot 187 which mayraise the hood 3 of the vehicle 13, a variation of which is illustratedin FIG. 37. The closed upper portion of the generally vertical slot 187may then function as a travel stop. The slot 187 may be configured suchthat the upper portion 189 of the hood hinge mechanism 181 may remain ina raised state which may cause the hood 3 to remain in a raised state.In one variation, the top of the slot 187 of the hood hinge mechanism181 may include a tapered wedge feature 189, a variation of which isillustrated in FIG. 36.

In another variation, the upper portion 201 of a hood hinge mechanism207 may be pushed upwards during deployment of the pedestrian protectionairbag module 81, a variation of which is illustrated in FIG. 39. Theupper portion of the hood hinge mechanism 201 may be connected to thelower portion 203 of the hood hinge mechanism 193 by a bolt 197 whichmay be seated in two vertical slots 198, 204, a variation of which isillustrated in FIG. 38. The upper end of the vertical slot 204 on theupper portion 201 of the hood hinge mechanism 193 may be tapered forward205 and the bottom end of the vertical slot 198 on the lower portion 203of the hood hinge mechanism 193 may be tapered rearward 199 so that thebolt 197, and the tapered slot ends 205, 199 interlock and the hood 3does not rise as the hood 3 is driven rearward in the case where theairbag module 81 does not deploy during a frontal impact. Also in thisvariation, a variation of which is illustrated in FIG. 38, the bolt 197may rest on the top of the vertical slot 204 and the bottom of the slot198, which may form the pivot point for the hood 3 when it is opened andshut during normal operation. Then, when the hood 3 may be raised viadeployment, the bolt 197 may move to the opposite side of both slots198, 204 which may allow the hood 3 to move up a height that isapproximately the length of both slots 198, 204 combined, a variation ofwhich is illustrated in FIG. 39. In a number of variations, the oppositeside of both slots 198 and 204 may also be angled to help maintain thehood orientation during loading when the hood 3 has been raised upwardduring deployment.

In another variation, the slot 199 and the surrounding bracket on theupper portion 201 of the hood mechanism 207 may extend down and adjacentthe vehicle body portion to which the lower bracket 203 mounts, whichmay enable additional hood 3 upper travel. The downward extension may bebeside the vehicle body 13 or it may be through a slot in the vehiclebody (not illustrated). In either case, the hood 3 and associated upperportion 201 of the hood mechanism 207 may be able to move through theirrange of rotational travel when the hood mechanism 207 pivots about itspivot that is represented by a bolt 197, a variation of which isillustrated in FIG. 38.

In another variation, the hood hinge mechanism 207 may be configured ina way which may hold the hood 3 in its undeployed state, a variation ofwhich is illustrated in FIGS. 40 and 41. The hood hinge mechanism 207may have a cutout 211 which may mate with a retention feature 209 thatis attached to a bolt which may be seated in a vertical slot 213 whichmay be located in the hood hinge mechanism 207. When the hood 3 islifted by a hood lifting device, the retention feature 209 may deformwhich may allow the bolt 197 to travel in the vertical slot 213.

In another variation, any of the hood hinge assemblies illustrated inFIGS. 36-41 may also be moved to the hood lifted state by one or moreseparate pyrotechnic devices that may not be part of an airbag module 81including, but not limited to, one or more dedicated hood lifters.

Referring to FIGS. 42-45, in a number of variations, an inflator 129 mayinclude a telescoping nozzle 215. The telescoping nozzle 215 may belocated below the hood 3 or hood hinge system 225 a variation of whichis illustrated in FIG. 44. When the inflator 129 deploys, gas 217 may bereleased from the inflator 129 a variation of which is illustrated inFIGS. 43 and 45. This may cause the telescoping nozzle 215 to pushagainst the hood hinge system 225 or directly against the hood 3 whichmay cause the hood 3 to rise. The inflator 129 may also include a radialprotrusion 227 which may act as a stopping feature to catch the bent lip216 on the telescoping nozzle 215 which may prevent the telescopingnozzle 215 from disconnecting from the inflator 129.

The cushion assembly 55 may include a layer 219 routing between thetelescoping nozzle 215 and the hood 3 or hood hinge system 225 and mayinclude at least one additional layer by sewing a sacrificial patch ofmaterial (not illustrated) onto the cushion assembly 55. This mayprotect or lessen the effect that the inflator gases 217 may have on theintegrity of the cushion assembly 55. The sacrificial patch may alsoprotect the cushion assembly 55 from contact with objects on the vehicleincluding, but not limited, to the windshield wipers, hood edge,deployment door edge, and/or the fender edge 341. The telescoping nozzlemay be mounted outboard of the hood hinge system 225, as part of one ormore pedestrian protection airbag modules 81 located in the fenderregions of a vehicle 1. The telescoping nozzle 215 may also be mountedinboard of the hood hinge system 225 and may push up on the hood 3 orthe hood hinge system 225 at a location inside or between the left andright hood hinge systems 225.

In another alternative, the telescoping nozzle 215 may alsosimultaneously push up on a portion of the fender, a portion of theA-pillar, a portion of a deployment door, and/or a portion of anadjacent trim piece that may cover a gap between adjacent components inthe region of the inflator (not illustrated). In another variation, thetelescoping nozzle 215 may rest against the bottom of the module 81 andsurround the lower part of the inflator such as with inflator and moduleconfigurations as illustrated in FIGS. 26-27 and FIGS. 32-33. Upondeployment the telescoping nozzle 215 may direct the inflator gas intothe cushion 55 in a controlled manner while the inflator rises upward.

Referring to FIG. 46, in a number of variations, the housing 143 mayinclude a structural outer element 229 which may help to direct thetrajectory of the cushion assembly 55 during deployment. The structuralelement 229 may also reduce lateral expansion or bellmouthing of thehousing 143 and may comprise any number of materials including, but notlimited to, steel or other materials which may not stretch underloading. The structural element 229 may completely surround or ring thehousing 143 and function like a band of material. Alternatively, thestructural element may be a U-shaped piece that is attached to thevehicle body 13 or a module mounting bracket 460 on the sides of themodule 81.

Referring to FIGS. 47-48, in a number of variations, a portion of thecushion assembly 55 may be configured to at least partially deploy fromunder a portion of a raised hood. The cushion assembly 55 may interactwith a portion of the underside of the hood 3 and may at least partiallypush it up. The hood 3 may have a frangible hood hinge assembly 231containing an element such as a frangible fastener (not illustrated)which may break or release during deployment of the pedestrianprotection airbag assembly 81 which may allow the hood 3 to rise. It mayalso include a hood linkage that may bend in a manner which may allowthe hood to rise. In another variation, a separate pyrotechnic device ormultiple devices may deploy to lift the hood 3, and the cushion assembly55 may be configured to at least partially interact and partially fillon the underside of the hood 3, a variation of which is illustrated inFIG. 47. In yet another variation, the cushion assembly 55 may beconfigured, such as with a cushion portion like 111, to fill a gap aftof the hood 3 in a raised position, a variation of which is illustratedin FIG. 48.

In another variation, a pedestrian protection airbag module 81 may bemounted in the fender region 1 laterally adjacent and below the hood 3and forward of the vehicle side door 11 and may deploy through adiscrete deployment door 19, which may be mounted adjacent the hood 3and the fender 9, a variation of which is illustrated in FIG. 1.

Referring to FIGS. 49-54, in a number of variations, a pedestrianprotection airbag module 81 may be constructed and arranged to deploythrough a discrete deployment door 19 when deployed. The discretedeployment door 19 may include at least one snap feature 247 which mayattach to the vehicle 13 in a number of locations including, but notlimited to, a fender 9, a body structural member, or the hood 3. Thesnap features 247 on the discrete deployment door 19 can be either malefeatures, as shown in FIGS. 49-50, or female features (not illustrated).The snap features 247 may also have a weakened region that may bedesigned to break or separate into pieces when experiencing the forcestransmitted to it during deployment. In one variation, if the discretedeployment door 19 snaps into the hood 3, the discrete deployment door19 may be constructed and arranged to seat against the fender 9 and/orother vehicle body structure so that the discrete deployment door 19 maymove with the hood 3 when the hood 3 may open. The discrete deploymentdoor 19 may also include a plurality of attachments around itsperiphery. The discrete deployment door 19 may be attached to thevehicle 13 in any of a number of variations including, but not limitedto, a mechanical fastener. The pedestrian protection airbag module 81and the discrete deployment door 19 may be assembled into the vehicle 13in any number of variations including, but not limited to, from abovethe vehicle 13. The pedestrian protection airbag module 81 may beattached to the vehicle 13 with the use of at least one mechanicalfastener. The mechanical fastener may include, but is not limited to, apositioning feature, a snap feature, and/or a threaded fastener. Thediscrete deployment door 19 may be attached to the vehicle 13 in any ofa variety of locations including, but not limited to an A-pillar 7, atrim piece adjacent the hood, a fender, or a vehicle door. In any of thecases described herein, the discrete deployment door 19 may remainattached to one adjacent structure or piece and separate or detach fromother adjacent structures or pieces during deployment. The discretedeployment door 19 may also be designed to separate from all adjacentstructures or pieces during deployment.

The discrete door 19 may alternately be attached to the pedestrianprotection airbag module 81 in any of a variety of ways including, butnot limited to a hook 247 and window feature 248, a variation of whichis illustrated in FIG. 51 with a window feature 248 on the discretedeployment door 19. The discrete deployment door 19 may be configured tobe shingled with surrounding surfaces and attachments which may preventwater from contacting the pedestrian protection airbag module 81. Thediscrete deployment door 19 may include an attachment feature 237 whichmay accept a tether assembly 235, a variation of which is illustrated inFIG. 50. In another variation, a tether 235 may be integral to thediscrete deployment door 19 and may retain the discrete deployment door19 to the vehicle body 13 during and after deployment of the airbagmodule 81 when the end 238 opposite the end secured to the attachmentfeature 237 is attached to the vehicle 13 or a component attached to thevehicle 13, such as a fender 9 or adjacent trim piece. In this manner,if the discrete deployment door 19 completely or partially detaches fromthe vehicle 13 during deployment, it may remain retained to the vehicle13 by the tether 235.

In yet another variation, a tether 235 may be attached to the discretedeployment door 19 using a threaded fastener (not illustrated). Thediscrete deployment door 19 may also include an emblem 239, a variationof which is illustrated in FIG. 49. The discrete deployment door 19 mayinclude at least one tear seam 249 which may be located on a non-visiblesurface 250 of the discrete deployment door 19. In another variation,the tear seam 249 may be located on a visible surface 251 of thediscrete deployment door 19. During deployment, the tear seam 249 maybreak apart allowing at least a portion of the cushion assembly 55 todeploy out of the discrete deployment door 19. Note that a tear seam 249may be present on a discrete deployment door 19 that attaches to thelower module housing body 243, as shown in FIG. 52 or that mounts to thevehicle 13 and surrounding components, such as the deployment doorrepresentation in FIGS. 49-50.

In yet another variation, tether 235 may have a curved or hooked end atone or both of the ends that routes through a hole, one slot, or twoslots in the mating attachment surface. In another variation, the tether235 may have a loop in the middle that shortens it in the undeployedstate and which pulls out as the tether 235 stretches to full lengthupon deployment.
